Subject: [PATCH] drm/vc4: hdmi: Raise the maximum clock rate
|
|
|
|
Now that we have the infrastructure in place, we can raise the maximum
|
|
pixel rate we can reach for HDMI0 on the BCM2711.
|
|
|
|
HDMI1 is left untouched since its pixelvalve has a smaller FIFO and
|
|
would need a clock faster than what we can provide to support the same
|
|
modes.
